Once zebra mussel eggs are fertilized they become microscopic larvae that float freely in the water for up to a month. Because these larvae are invisible to the naked eye, boaters must drain all water between lakes to prevent their transportation in residual water in live wells, bait buckets, ballast tanks, and bilges.
As zebra mussels mature into adults, the larvae become settlers at a size of only 1/100th of an inch and start to attach to hard surfaces, but are hard to see. Using tiny, root-like fibers called byssal threads, the young settlers bond to boats, docks, floats, rocks, plants, pipes, and any other hard surface or crevice in the water.
Zebra mussels grow rapidly to a maximum shell size of about 1.5 inches and can reach densities of more than 700,000 individuals per square yard. They heavily impact hydroelectric facilities and other infrastructure located in or drawing water from infested waters. Although zebra mussels live for only 1.5 to 2 years in Texas, they can start reproducing within the first year of life at about 1/3 inch long. Please encourage tenants to call our 24/7 hotline at (512) 389-4848 to ask for guidance before a boat is moved from a marina on a lake with zebra mussels!
